Numerical simulations of internal shocks in spherical geometry: hydrodynamics and prompt emission

A. Charlet, J. Granot, P. Beniamini

Among the models used to explain the prompt emission of gamma-ray bursts (GRBs), internal shocks is a leading one. Its most basic ingredient is a collision between two cold shells…

Detection of X-ray Emission from a Bright Long-Period Radio Transient

Ziteng Wang, Nanda Rea, Tong Bao +46

Recently, a class of long-period radio transients (LPTs) has been discovered, exhibiting emission on timescales thousands of times longer than radio pulsars. Several models had bee…

Features and prospects for kilonova remnant detection with current and future surveys

Sandeep Kumar Acharya, Paz Beniamini, Kenta Hotokezaka

We study the observable spectral and temporal properties of kilonova remnants (KNRs) analytically, and point out quantitative differences with respect to supernova remnants. We pro…

Extragalactic Magnetar Giant Flare GRB 231115A: Insights from Fermi/GBM Observations

Aaron C. Trigg, Rachael Stewart, Alex Van Kooten +22

We present the detection and analysis of GRB 231115A, a candidate extragalactic magnetar giant flare (MGF) observed by Fermi/GBM and localized by INTEGRAL to the starburst galaxy M…

Rapid Response Mode observations of GRB 160203A: Looking for fine-structure line variability at z=3.52

G. Pugliese, A. Saccardi, V. D Elia +26

Gamma-ray bursts are the most energetic known explosions. Despite fading rapidly, they allow to measure redshift and important properties of their host-galaxies. We report the phot…

On non-detection of Gamma-Ray Bursts in three compact binary merger events detected by LIGO

Luyanda Mazwi, Soebur Razzaque, Lutendo Nyadzani

The joint detection of the gravitational wave (GW) event GW170817 and the short-duration gamma-ray burst (SGRB) event GRB 170817A, marked the beginning of GW multi-messenger astron…

Galactic transient sources with the Cherenkov Telescope Array Observatory

Cherenkov Telescope Array Observatory Consortium

A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…

Concise Spectrotemporal Studies of Magnetar SGR J1935+2154 Bursts

Ozge Keskin, Ersin Gogus, Yuki Kaneko +6

SGR J1935+2154 has truly been the most prolific magnetar over the last decade: It has been entering into burst active episodes once every 1-2 years since its discovery in 2014, it…

Deep Neural Networks for Estimation of Gamma-Ray Burst Redshifts

Tamador Aldowma, Soebur Razzaque

While the available set of Gamma-ray Burst (GRB) data with known redshift is currently limited, a much larger set of GRB data without redshift is available from different instrumen…

A JWST Survey of the Supernova Remnant Cassiopeia A

Dan Milisavljevic, Tea Temim, Ilse De Looze +43

We present initial results from a JWST survey of the youngest Galactic core-collapse supernova remnant Cassiopeia A (Cas A), made up of NIRCam and MIRI imaging mosaics that map emi…
